2,845,295 DOOR HASP William Clarke, West Hollywood, Fla. Application April 29, 1954, Serial No. 426,526 1 Claim. (Cl. 292-281) The present invention relates to a door hasp and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

Generally the present invention consists of a door hasp comprising a pair of complementary members each formed of a single piece of flat metal and each having a base plate and an outwardly extending apertured pro jection. The device is such that it may be mounted with the base plate of one of the members aflixed to a door while the base plate of the other member is aflixed to the door jamb immediately above or immediately below the first-mentioned base plate. The device is adapted to be made of thin metal so that no alternation of the door or jamb is necessary in the average case in order to mount the device. When the device is mounted as just described, the projections will align in face-to-face registry so that, when the door is in closed position, a padlock may be inserted through the apertures in the projecting portions to thus lock the door. In the preferred form of the invention, the projections are integrally connected with the bases in each case by means of a shoulder which permits them to lie in a parallel but slightly offset plane to the base with which they are associated, thus preventing any interference between such projections when the door is opened or closed. However, it is pointed out that in each of the members, such members may be formed of material which is flexible sutficiently to permit outward yielding of each of the projections when they come into contact with each other upon opening or closing of the door thus permitting manufacture of the device without the aforesaid shoulder.

It is accordingly an object of the invention to provide a device of the character set forth which is simple in construction, inexpensive to manufacture and yet effective and efficient in use.

Another object of the invention is to provide a door hasp which may be atached to a door and door jamb with a minimum or no alteration of such door and jamb.

Another object of the invention is to provide, in a device of the character set forth, a pair of members each of which may be formed of a single piece of flat thin metal.

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:

Figure l is a plan view of a door mounted in a door jamb, the latter being shown in section, the door being shown partially open and illustrating an embodiment of the invention attached to such door and jamb,

Figure 3 is an enlarged fragmentary sectional view taken along line 33 of Figure 1,

Figure 4 is a fragmentary sectional view taken along line 4-4 of Figure 3,

Figure 5 is a fragmentary sectional view taken along line 55 of Figure 3,

Figure -6 is a fragmentary sectional view taken along line 6-6 of Figure 3, and

Figures 7 ;and 8 are perspective views of a pair of members forming the hasp of the present invention.

Referring more particularly to the drawing, there is shown therein a door 10 hinged, as indicated at 11, to a door jamb 12 and provided at its free end portion with conventional knobs 13. A door jamb 14 is also provided and is equipped with a conventional doorstopping shoulder lS.

' The device embodying the present invention consists of a pair ofrnembers each identical in its'construction, one of which is generally designated at 16 and adapted to be attached to the door 10 while the other is generally designated at 17 and is adapted to be attached to the door jamb 14.

The member 16 is provided with a base plate 18 having a plurality of openings 19 extending therethrough and preferably countersunk whereby the same may be attached to the door 10 by screws 20 and having formed integrally therewith an outwardly extending projection 21 having an aperture 22 therein which projection 21 extends upwardly as well as outwardly from its point of juncture with the base plate 18, as indicated at 22a. A shoulder 23 may, if desired, integrally interconnect the base plate 18 and the projection 21 to thus place the projection 21 in a plane parallel to but slightly offset from the base plate 18.

The member 17, which is identical in all respects to the member 16 but which is reversed when attached to the jamb 14, is provided with a base plate 24 having a plurality of openings 25 therethrough which openings are countersunk and which permit the plate 24 to be attached to the jamb 14 by means of screws 26. Extending outwardly from the base plate 24 and integrally formed therewith is a projection 27 having an aperture 28 therethrough. The projection 27 extends downwardly, as indicated at 29a, from the point of juncture with the base plate 24 and a shoulder 29 may integrally interconnect the plate 24 and the projection 27 to place the latter in a plane parallel to but slightly oifset from the plate 24.

In operation, it will be apparent that the member 16 may be aflixed by the screws 20 to the free end por tion of the door 10 as clearly illustrated in Figure 2 while the member 17 may be aifixed to the door jamb 14 in such manner that the base plate 18 underlies the base plate 24 and, in ordinary circumstances, the base plates 18 and 24 will lie in the same plane, as indicated in Figure 4, thus taking advantage of the ordinary space, indicated at 30, in Figure 4, which is conventionally left between the door 10 and its jamb 14 and thus permitting the mounting of the members 16 and 17 in the manner set forth without the necessity for altering either the door 10 or the jamb 14 in any manner whatsoever. When the members have been so mounted, it will be apparent that the projections 21 and 27 will lie in faceto-face relationship or registry when the door is in closed position, as shown, for example, in Figure 6 of the drawing. When the projections 21 and 27 are in such registry, it will also be apparent that the apertures 22 and 28 will likewise be in registry so that a padlock, indicated in dotted lines at 31 in Figures 3 and 5, may be inserted therethrough to thus securely lock the door 10 to the jamb 14. It will also be apparent that the shoulders 23 and 29 permit the projections 21 and 27 to come into such face-to-face relationship without interfering one with the other during the opening and closing of the door. However, it is stressed that if the members 16 and 17 be made of a thin flexible metal,

3 such shoulders 23 and 29 will be unnecessary since the projections 21 and 27 will then yield one to the other to assume the face-to-face relationship shown, for example, in Figure 6, the operation of the device being otherwise identical as above set forth.

While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claim.

What is claimed is:

For use with a door and its associated jamb, a pair of duplicate complementary members each having a base plate, an outwardly extending apertured projection,-

and a shoulder angularly and integrally interconnecting the plate and projection whereby they lie in parallel but slightly spaced planes, one of said projections extending downwardly, the other of said projections extending upwardly, one of said base plates attachable to he ree ed e 9f the 5199; t e ot e ba P a attachable to the jamb vertically adjacent to the base plate attached to the door, with said projections in face-t0- face registry when said door is in closed position relative to said jamb, whereby a padlock may interconnect said projections.
